HENRY H. SCIPLE, OF SAN FRANCISCO, CALIFORNIA, ASS'IGNOR OF ONE- HALF TO STEPHEN MAHONEY, OF MINNEAPOLIS, MINNESOTA.

VIBRATOR.

Specification of Letters Patent.

Patented June 1 1, 1907.

To a. whom. it may concern:

Be it known that I, HENRY M. SCIPLE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Vibrators, of which the following is a specification.

This invention relates to vibrators or exhilarators and is especially designed for the use of people generally having'pains in any portion of the body, the instrument being useful in cases of neuralgia, rheumatism and the like.

One object of the present invention is to provide a simple, inexpensive hand-operated instrument to take the place of the large expensive machines operated byelectricity or other power.

A further object pf the invention is to provide for variety of actions, so that the parts affected may be directly operated upon and the blows or vibrations regulated to suit the needs of the patient.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arran ement of parts hereinafter more fully described, illustrated and claimed.

In the drawings, Figure 1 is a sectional elevation of a vibrator embodying the present invention. Fig. 2 is a plan view of the same, showing the gear housing or case 'in section. Fig. 3 is a longitudinal sectional view of one end of the vibrator. Fig. 4 is a cross-section ing or unbalanced wheel.

Referring to the drawings, 1 designates the main handle of the implement upon which all of the operative parts of the device are mounted. The shank or stock of the device embodies the parallel side bars or plates 13 which are secured to the handle 1 and in which bearings are formed for a shaft 14 which is operated by a suitable crank handie 2.

Mounted fast on the shaft 14 is a spur gear wheel 15 which meshes with a pinion 16 on a short counter-shaft 17 journaled in hearings in the bars 13 and having fast thereon a bevel gear wheel 18 which meshes with a pinion 19 hollow section 9 of the stock or shank, the

said shaft 5 being journaled in bearings 20 and 21 located at opposite ends of the tubular or hollow portion 9 of the stock.

Mounted upon the projecting end portion of the shaft 5' is a'fioating or unbalanced wheel 3 which is shown in plan view in 5 as provided with a slot 22 which. extends from the center of the wheel outward radially any suitable distance to give the wheel an eccentric relation to the shaft for causing the same to wabble and float back and forth during the rapid rotation of the shaft 5. The extremity of the shaft 5 is threaded to receive a lock-nut '8 by means of which, if so desired, the wheel 3Imay be clamped firmly on the shaft and up against a shoulder 23 on the shaft 5 outside of the end bearing 20,-as

shown in Figs. 3 and 5. 4

10 designates a collar which fits around the hollow or tubular port1on 9 of the stock and is adjustable thereon both lengthwise of the part 9 and also around the same. collar 9 carries a tubular boss or guide 11 in which is mounted the reciprocatory stem or plunger 6 of a contact cup or head 7 adapted to rest against the body of the patient.

12 designates a spring which encircles the stem or plunger 6 within the uide 11 and: which is interposed between t e outer end of the guide and a shoulder 24 on the stem or plunger, whereby the inner end of said stem is urged inward and held in enga e- The ment with a cam 4 fast on and carried by t e rotary shaft 5, said cam acting to impart a reciprocatory movement to the stem or plunger 6. The cam 4 is stepped or, in other words, provided with several ortions having different degrees of eccentncity for imparting more or ess reciprocation to the stem or plunger 6, according to the severity or violence of the blow required which varies in accordance with the needs of the patient.

In order to provide for adjusting the collar 10, the tubular stock section 9 is provided with a plurality of holes 25 inline with the different steps of the cam, as clearly shown in Fig. 1, so that the stem 6 may be brought into operative relation to an one of said steps. It will also be observe that the art 9'18 provided with additional perforations 26 arranged in circular series so that the collar may be turned upon the art 9 and secured at any desired point to o ange the re- ICC I lation between the operating crank handle 2 which are turned into a vibrating,

and the cup 7 so that said cup may be disposed at any one of a number of oints around the stock of the instrument to etter facilitate the application of the vibrations to the body. This adjustment of the collar 10 is also valuable in order to enable a patient to use the instrument upon himself.

From the foregoing description, it will be seen that I obtain several different degrees of vibration and am able to produce either regular or irregular motions and temper or regulate the violence of the hammer blow action of the contact cup or head, increasing or decreasing the shocks at will and regulating the wave motions created by the rapid rotation of the shaft and the reciprocation of .the plunger and rotation of the unbalanced wheel. There are three positive means of producing an irregular movement on the cup or head while applied to the body, all of oscillating or. reciprocating motion, one acting inopposition to the other to produce an easy or violent vibration, as needed. When greater vibration is desired, the jam nut is loosened andthe unbalanced wheel moved away from the center, after which the nut is tightened. If less vibration is desired, then the wheel is moved to. a more central position. It will be understood that the steps of the cam may be of any desired shape in cross-section so as to produce an eccentric which may be the round, oval or polygonal shaped. The operating crank handle may be turned in either direction as may be found most convenient, the cam being heavier on one side than on the other, under rapid rotation produces a motion of the whole structure while the eccentric produces a reciprocating motion which may be tempered or modified and refined to produce the desired result. I

I claim: 1. A manually operated vibrator embody- 'ing a rotary shaft, a tubular stock provided with holes, a collar movable axiallyarou'nd and also lengthwise of said tubular stock, and a contact cup or head provided with a plunger stem insertible through any one of said poles in the tubular stock and working in contact with the cam.

. 2. A manually operated vibrator embodying a tubular portion, a rotary shaft, a stepped cam thereon, a contact cup or head having a stem working in contact with said cam, said tubular portion having openings for adjusting said stem to cooperate with any one of the steps of the cam. In testimony whereof, I afiix my signature in presence of two witnesses.
